POST route in Leaflet map giving errors

Is there any way to use a form in leaflet mapping to open another page?
I'm using a post route for this and have even tried embedding it in an tag but to no avail.
At the moment the form data is in a for loop like so
map_data.forEach(element => {
console.log('program=' + element.program + ', lat=' + element.gps_lat + ', long=' + element.gps_lon);
data[i] = L.marker([element.gps_lon, element.gps_lat], {icon: redIcon}).addTo(map);
var url = '{{ route("opentraining", ":training_id") }}';
var alt_url = '{{ route("opentraining") }}';
url = url.replace(':id', element.id);
data[i].bindPopup(
'<strong>' + element.program + '</strong>'
+ '<br />'
+ '<b>Location:</b> ' + element.location + ', ' + element.district + ', ' + element.province
+ '<br />'
+ '<b>Description:</b> ' + element.description
+ '<br /><br />'
+ '<form onsubmit="' + alt_url + '" method="POST" class="formEditTraining">#csrf<input type="hidden" name="training_id" value='+ element.id + '>'
+ '<button type="submit" value="submit" class="btn btn-primary trigger-submit">View Record</button>'
+'</form>'
).openPopup();
i++;
});
Even when use the route directly within the form it makes no difference all I get is an error saying POST method isn't supported.. What could I be missing ?

You're using the wrong attribute for the URL in your <form> tag. onsubmit is for specifying a JS function to run before the form is submitted. To specify the URL you want to submit the form to, use action. Since you are not specifying action at the moment, it's posting it back to the same URL that the form is on, which evidently is not set up to receive POSTs.

How to escape a string with additional paramer?

I am trying to escape a string and it currently looks like this:
... onclick="anotherfunction(\'bla\',\'bla\'); myfunctionhere(\'/path1/path2/\'' + val.param1 + '\', \'' + val.param2 + '\', \'' + val.param3 + '\')";
Something is still wrong with it because val.param1 is there but still with an additional ' in front.
Lets say val.param1 is 4711 then the first part of myfunctionhere is being renders as
/path1/path2/'4711
How do I solve this? Removing the second ' does not help.

Ah, got it working right now:
... onclick="anotherfunction(\'bla\',\'bla\'); myfunctionhere(\'\/path1\/path2\/' + val.param1 + '\', \'' + val.param2 + '\', \'' + val.param3 + '\')";

SharePoint ToC script - changing link style to headers

I'm working on online SharePoint site, where I want to have Table of Contents on my pages. It went successful, but I'm not satisfied with links to headers, which are in this style: PageName#heading_[number], where I would like to have PageName#{headingName}.
Is it possible? Here is link to my script: https://pastebin.com/MVsJf0hr . I suppose that it must be written somewhere here:
$(this).attr("id", "heading_" + i);
$("#theTOC").append("<a href='#heading_" + i + "' title='" + theLevel + "'>" + theLevelString + " " + $(this).text() + "</a><br />");

Can´t get the output using jQuery with rest

I am using jQuery with REST in my application and I want to get the ouput mentioned below using the jQuery within my webpage .
I used the code below to search by get a company by id (each company has id, name other info supplier and buyers) but the result does not show up for me with my code, any suggestion on what have I missed?
REST is a concept for HTTP request exchange, so you're making RESTful request calls (e.g. 'get') against the REST-API you implemented on server side.
<input name="find" type="text" maxlength="300" id="find"/>
<button onclick="findId()"> Find By ID </button>
<div id="info"></div>
<script>
function findId()
{
var id = document.getElementById("find").value;
$("#info").html("");
$.getJSON("http://localhost:8080/company/" + id, function(data)
{
for (var i in data) {
$('#info').append("<p>ID: " + data[i].id + "</p>")
$('#info').append("<p>Name: " + data[i].name + "</p>")
$('#info').append("<p>Other Info: " + data[i].otherInfo + "</p><br>")
$('#info').append("<p>Supplier: " + data[i].suppliers + "</p><br>")
$('#info').append("<p>Buyers: " + data[i].buyers + "</p><br>")
}
});
}
When I type http://localhost:8080/company/ into my browser I get the following output:
[{"id":1,"name":"Test 1","otherInfo":"Test 1","suppliers":[{"id":1,"name":"Test 1","address":"Test 1","buyers":[{"id":1,"name":"Test 1","address":"Test 1"}]},{"id":2,"name":"Test 2","address":"Test 2","buyers":[{"id":3,"name":"Test 3","address":"Test 3"},{"id":2,"name":"Test 2","address":"Test 2"}]}]},{"id":2,"name":"Test 2","address":"Test 2","suppliers":[{"id":3,"name":"Test 3","address":"Test 3","buyers":[{"id":4,"name":"Test 4","address":"Test 4"}]}]}]
If i type http://localhost:8080/company/1 into my browser i get
{"id":1,"name":"Test 1","otherInfo":"Test 1","suppliers":[{"id":1,"name":"Test 1","address":"Test 1","buyers":[{"id":1,"name":"Test 1","address":"Test 1"}]},{"id":2,"name":"Test 2","address":"Test 2","buyers":[{"id":3,"name":"Test 3","address":"Test 3"},{"id":2,"name":"Test 2","address":"Test 2"}]}]}

Is it a cross domain request? If so you can get around it by using jsonp instead of json.
function findId()
{
var id = document.getElementById("find").value;
$("#info").html("");
$.getJSON("http://localhost:8080/company/?callback=?" + id, function(data)
{
for (var i in data) {
$('#info').append("<p>ID: " + data[i].id + "</p>")
$('#info').append("<p>Name: " + data[i].name + "</p>")
$('#info').append("<p>Other Info: " + data[i].otherInfo + "</p><br>")
$('#info').append("<p>Supplier: " + data[i].suppliers + "</p><br>")
$('#info').append("<p>Buyers: " + data[i].buyers + "</p><br>")
}
});
}

Internet Explorer open outlook appointment javascript

Go figure, I am having issues with IE and was hoping someone might be able to help....
I have a site where visitors will come and sign up for a specific meeting and then I want to be able to generate an appointment for the calendar of their choice; the choices are gmail, yahoo, and outlook. The gmail and yahoo appointments are generated as expected in all browsers, but the outlook appointments work in every browser except IE. Instead of throwing a file save dialog, IE opens a new window and attempts to navigate the url.
I am using the iCalendar jquery library that I modified a bit and building the ics markup in javascript, like this
//build ics markup
var event = makeAppointment(settings);
//render ics markup as outlook appointment
window.open("data:text/calendar;charset=utf8," + escape(event));
function makeAppointment()
{
return 'BEGIN:VCALENDAR\n' +
'VERSION:2.0\n' +
'PRODID:jquery.icalendar\n' +
'METHOD:PUBLISH\n' +
'BEGIN:VEVENT\n' +
'UID:' + new Date().getTime() + '#' +
(window.location.href.replace(/^[^\/]*\/\/([^\/]*)\/.*$/, '$1') || 'localhost') + '\n' +
'DTSTAMP:' + $.icalendar.formatDateTime(new Date()) + '\n' +
(event.url ? limit75('URL:' + event.url) + '\n' : '') +
(event.contact ? limit75('MAILTO:' + event.contact) + '\n' : '') +
limit75('TITLE:' + event.title) + '\n' +
'DTSTART:' + $.icalendar.formatDateTime(event.start) + '\n' +
'DTEND:' + $.icalendar.formatDateTime(event.end) + '\n' +
(event.summary ? limit75('SUMMARY:' + event.summary) + '\n' : '') +
(event.description ? limit75('DESCRIPTION:' + event.description) + '\n' : '') +
(event.location ? limit75('LOCATION:' + event.location) + '\n' : '') +
(event.recurrence ? makeRecurrence(event.recurrence) + '\n' : '') +
'END:VEVENT\n' +
'END:VCALENDAR';
}

You can get the file save dialog to work in IE by adding a "Content-Disposition: attachment" response header. However, this must happen on the server and cannot happen in client-side scripting, since JavaScript cannot modify header information.
